Horn speakers are really bright?

I can say for sure that over my computer speakers, the opening guitar introduction sounds better to me on the original drivers. A little more dynamic and the timbre sounds more real.

It's hard for me to say because I get notably different impressions of the sound as you move the microphone small amounts. The very beginning audience clapping sounds very different, I'll say that. 

The new drivers are much better.  Vocals are more pronounced and the instrumentation cleaner and more pronounced.
